Description
Module with real time clock (RTC) RV3028. The board has large pads dedicated for "crocodile" cables, which facilitate connection to the micro:bit module. There is a socket with a 3 V lithium battery on the board, which maintains the operation of the system after disconnecting the power supply. The RV3028 chip uses a precision oscillator so that the timing error is much less than similar products. The module is supplied with the voltage of 3.3 V and communicates via the I2C interface. The product page includes the manual and sample programs.
